Introduction

This document describes a basic configuration that enables IPv6 on Cisco Adaptive Security Appliance (ASA) in order to pass the IPv6 packets. This configuration is shown using the Adaptive Security Device Manager (ASDM). Support on Cisco ASA for the IPv6 packets is available from Cisco ASA software version 7.0(1) itself. However, the support to configure through ASDM is available from Cisco ASDM software version 6.2 onwards.

Prerequisites

Requirements

There are no specific requirements for this document.

Components Used

The information in this document is based on these software and hardware versions:

  • Cisco ASA with version 8.2

  • Cisco ASDM with version 6.3

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.

Conventions

Refer to the Cisco Technical Tips Conventions for more information on document conventions.

Background Information

In order to pass the IPv6 packets through the ASA, complete these high-level steps:

  1. Enable IPv6 on the required interfaces.

  2. Define the IPv6 access-lists where required.

  3. Specify the IPv6 route information.

Configure

Complete these detailed steps.

Enable IPv6 on the required interface

  1. Choose Configuration > Device Setup > Interface, select the required interface, and click Edit.

  2. Click the IPv6 tab in order to specify the related IPv6 settings.
